To all 'whom it may concern.'

f -Beit known that I, Juntos E. Harrison-n, a 'citizen of "the United States, 4residing at Chicago, in 'the county of Cook and State of lIllinms, have invented certain new und use- -fnl improvements in Non-Skidding Devices, o'f which the 'following is a specification.

This invention relates to non-skid devices to 'be applied to rubber tires used on vehicles, such as a\1tombil es,ftoprevent the wheels from skidding in any direction, and to prevent 4`friction between the wheel and the surflaceof fthe 'ground in starting or stopping :the vehicle. One object of the invention is Iito -provide a suitable device for applying to the wheel which is of such a nature that it may be very quickly and easily applied or removed, and arranged so that it will be the slipping of the wheel on"'the surface o the ground under any ordinary circumstances. A further object i'sto rovide a device which will bc nolseless and) will be dependable, and one which-will not injure the rubber tire, and `which will not we'arout with any ordinary amount of use, or become broken or delr'anged.

4vofthe accompanying drawings Figure 1 is an elevation of a device. applied to a ivheel, which embodies features of my invention; Fig. 2 is a sectional view of the same along the'llne 2 2 of Flg. l; Fig. 3 1s a view of the underside of the device; and Fig. 4 is` an elevation of a similar device applied to -a solid tire wheel.

In veneral my non-skid device comprises a U-siaped shoe which is passed over the tire of the wheel with the arms extending radially inward, one on each side of the wheel, and with the ends of the arms-fastened to a collar or clamp which is held in place by the spoke oi' the wheel, or in any other suitable manner. shoes may be applied to the wheel as may he desired; but in practice two or three are suilicient, and one will ordinarily serve all purposes, particularly the purpose of preventing rotational slipping of the wheel on the road bed.

The shoe 10 comprises a heavy U-shaped strap with arms or Shanks l1 arranged to hold the Shoe on .hc wheel. The means which I'provide for holding the shoe vomprises a split collar 12 arranged to encircle the spoke ofthe wheel, it being understood that `the collar may be formed to fit any As muny of theseshape of spoke. The collariis'clam to thel spoke by means offtl1elugs-14, an :bolts 15,

vor in any other suitable manner. fExtending outwardly fromthe upper surface -of `the collar, on one side thereof, is a lug 16, 4hav'- mg a slot 17 theretl'xrougln and .one arm 11 of the shoe 1s adapted to ass through this slot. 0n the lower end o -each arm 1v1 isa 4hook 18. The shape ofthe slot 17 with 'reference to the hook -18 is suchthat when the4 arm 11 1s turned away romthe tire a een' tain distance the hook will passV down through the slot, but when the arm is moved over to its normal position adjacentthetire, :is shown in Fig. 2, the hook holds 'thearm from passing out of the slot. The shoe and the arms 11 are sofmade thatthey ,can be sprung sufficiently to allow the placing of the shoe over the tire after one 'arm :11 has been placed inthe slot 17.' The arms are similarly formed and the holding-means are so arranged-that either arm-'may b eplaedl .in either holding :Patented Mar. .1; 1921.

hinge 21 is such that the free end o f the plate. rises materially, and the hook 18 of the arm 11 mayvbe Aforced under the lower edge of the plate. The end 23 ofthe plate is then forcedhack against the arm Vto its.

normal position, thuspulling the shoe 10 snugly against the rubber tire; and a latch 24 is arranged so as to spring over the end 23 of the plate and hold the plate firmly in place. The pins 19'ixed to the collar pass through openings in the plate 22, and prevent upward movement of the plate or sidewise movement o f the arm 11. I n this manner the entire apparatus is held snugl so that there is no rattling of the parts an the shoe lits snugly on the tire, but without depressingv the tire inwardly; and it is to be understood that the inner surface of the shoe is arranged Ato come in contact at all points with the tire, being concave both transvvr ely und longitudinally in accordance willi the normal shape of the tire.

The arms 11 are thus held so as .to prevent any outward movement radinlly'of the shoe1 yet radial movement inward is not prevented, as the arms are free to pass inwardly 1n of the collar an the slot 17 andin the space formed between as it is the lug 20 and plate 22, so that when the wheel rotates, bringing the shoe on the road bed, the shoe is free to be pressed inwardly exce t as it is o posed by the 4pressure of the tire itself. is being so no appreciable jar is caused by the rotation of the wheel due to the shoe. In order to still furtherreduce any jarrin tendency, and for other reasons, I provi e 'the .outer surface of the shoe with stops 25, so that the outer portions of the shoe which come first in contact with theground are thin and will cause only a slight depression in the tire, and thus will prevent jarrin yet the central portions of the shoe are su ciently thick to produce very material friction on the surface of the ground, and revent skidding or undesirable rotation of tlie wheel thereon.

`In this manner I provide a derii' which is similar in its actionY to the ordinary nonskidding chain used on wheels, but one which does not have the disadvantage of causing injury to the tire, and which has enormous wearing qualities compared with the ordinary chain, and also one which can be very quickly applied or removal,

Fig. 4 lllustratcs a modification of -the Shoe applied to a solid tire. As the various parts are very similar |.o the corresponding p'al'ts of the shoe as applied to the pneumatic tire, a special description of this modification is not t ought necessary. lt is to he under- Stood also that other modifications inthe device could be made by those skilled in thrart without departing from thc spirit of the.invention as disclosed by the follow- Ii claims.

claim as mv invention:

1. Y.A non-skid device for rubber tired wheels comprising a shoe, hai/'iupr arms ada ted tcextend inwardly on opposite sides,l of t e tire, similar angular projections fixed to the outer en ds nl' the arms, a collar arran d to encirch` the outer end of a spoke of i wheel, lu projecting from each side the respective arm projections. and means connected with one of; said lugs for` pulling inwardly on the corresponding projection adapted to receive and hold placed in the holding position with reference to the lug. y

p 2. Anon-shielding device for rubber tired wheels comprising 'a U-shaped member having two arms', an angular projection on the end of each o''V said arms, means adapted to be fixed to the wheel for holding the inner ends of said arms, said means comprising a plate hinged to said holding means, said linge bein placed angularly so that the free end o said Aplate mores outwardly radially as the'end is moved outwardly from the holding means, whereby the pro'ection on one of the arms can he passed un er the plate and the will hold the shoe snuglyin place.

3. A non-skidding device comprising a U- shaped shoe arranged to pass over the 'tire of a wheel with its arms extending inwa rilly. and means for holding 4the said shoe on the wheel. the shoe being materially thicker near the centraL portions than near the edges, the oute'r sui-face formed o'f steps running longitudinali of the .shoe.

4. A uon-skidding device for-wheels comprising a shoe adapted to be placed over the tire of a wheel, said shoe having an arm arranged to extend inwardly on each s'ide of the tire, shoe holding means arranged to be fixed to the wheelwith a lug extending on each side of the Awheel, one of the lugs haring a radial openin therethrough adaptplate when forced inwardly- .ed to receive one of saxdarms which has an 1 angular projection o`n its end for holding s the arm inthe opening, and means on the other lu pulling t e shoe tight y against theV tire.4

5. A non-skidding device for wheels comprising a shoe adaptedto be placed over thetire of a wheel, arms fixed to said shoe and arranged to extend on opposite sides of said tire, similar projections fixed an l larh7 to the outer ends 'of said arms, `oe hol in g means arran ed to be fixed to, the wheel, and means fix to said holding means for grasping and pulling on said projections. 1 Ir:1 testimony whereof.
